HENRY ZERFFI, OF LONDON, ENGLAND.

VENTILATING HATS.

SPECIFICATION forming part of Letters Patent No. 354,004, dated December 7. 1886.

Application filed October 11, 1-884. Serial No. 145,265.

To all whom it may concern:

Be it known that I, HENRY CHARLES ZERFFI, of the firm of Macqueen and Company, of 14 and 15 Long Lane, Aldersgate street, in the city of London, England, hat-mannfacturer, a subject of the Queen of Great Britain, have invented certain new and useful Improvements in Ventilating Hats. (for which English Letters Patent No. 12,302 were granted to me, dated September 11, 1884.) of which the following is a specification.

My invention relates to improvements in those hats in which air is admitted to the interior of the hat through the hat-band,while the dust is excluded.

My improvement consists in the means for ventilating hats hereinafter described, and pointed out in the claims.

Myinvention is represented inthe accompanying drawings,in which like parts are marked with similar letters of reference.

Figure l is a vertical section, and Fig. 2 a horizontal section, of a hat provided with my means of ventilation. view of a portion, and Fig. 4 is a vertical sec tion of a portion, of a felt hat. Fig. 5 is an interior view of a. portion, and Fig. 6 is a vertical section ofa portion, of a helmet.

a is the body of the head-covering, in which are formed slots b, providing long and narrow apertures running parallel with the brim a of the head-covering. The body a may-have a covering, 0, of silk or be formed of felt.

d is the hath-and, which may consist of an ornamental covering.

6 is the lining or sweat-band, having perforations or openings 6, registering with the slots in the body. Instead of, or in addition to the erforations e I sometimes leave'a Fig. 3 is an interior.

space, 6', between the body a and the lining up or sweat e.

f is a band of filtering material between the body a and sweat e.

In all cases the hat-band covers the slots b, so as to form a filter for the air.

In Figs. 1 and 2 the silk covering cextends over the slots to provide an additional filtering-band, and the sweat has additional perforations, c, surrounding those that register with the slots b. In Figs. 1 and 2 the slots 1) are cut right through the silk covering, to permit the air to pass more freely into the interior of the hat.

I prefer to form the filtering material f of flannel or medicated material. or it may be a band having suitable antiseptics applied thereto.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:

1. The conibinai ion ofa body,a. formed with H. O. ZERFFI.
